Message : WebGL requires GL_FRAMEBUFFER_UNSUPPORTED for identical FBO attachments. If the same level of a texture is attached to multiple color attachments of a framebuffer object, for example, the WebGL conformance tests require generating a GL_FRAMEBUFFER_UNSUPPORTED error. The Direct3D backend already had this restriction; apply it to all backends when the WebGL compatibility extension is enabled. Fixes the following WebGL conformance tests with the pass-through command decoder in Chrome: conformance/extensions/webgl-draw-buffers-framebuffer-unsupported conformance2/rendering/framebuffer-unsupported BUG=angleproject:2168 Change-Id: I340d06ca0ee969989c6c5725512b1b9542281477 Reviewed-on: https://chromium-review.googlesource.com/699856 Commit-Queue: Kenneth Russell <kbr@chromium.org> Reviewed-by: Geoff Lang <geofflang@chromium.org>
